Reblog via :thilo:
I was inspired by this great write-up on operating your own email server by @jwildeboer : https://jan.wildeboer.net/2022/08/Email-0-The-Journey-2022/ (Worth a read!). So I sat down and built some automation around this excellent blog post.
Long story short here's "version 0.1" of a dockerised mailservice: It features SMTP and IMAP servers, supports TLS (via letsencrypt), DKIM/DMARC for sending and receiving, and comes with a monitoring suite.
Set-up requires only minimal configuration.
